On one hand, Weinberg's argument [1] and the possibility of cosmological in􀀍ation and vacuum tunneling in a multiverse 􀀌t naturally with the many vacua of string theory into an anthropic explanation for the observation of a small but nonzero cosmological constant, roughly 10 􀀀120 in natural units [2] . On the other hand, there is as yet no sound methodology for computing the relative abundance of di􀀋erent string vacuum solutions, and we are far from a complete understanding of the full set of possible vacuum solutions with supersymmetry, let alone of those without supersymmetry.  \nThe largest numbers of di􀀋erent string vacua studied to date arise in the form of \\􀀍ux compacti􀀌cations\" [3{5] . A 􀀍ux compacti􀀌cation is a string compacti􀀌cation on a geometric space M, combined with a choice of generalized p-form 􀀍uxes, analogous to magnetic 􀀍ux, that thread various topological cycles on M. In general, the set of 􀀍uxes is constrained by a tadpole condition (e.g., from varying one of the 􀀌elds in the Lagrangian in a supergravity approximation) so that the number of 􀀍ux vacua that can arise for any given geometry becomes bounded, though it can be exponentially large. For type IIB string theory, the number of 􀀍ux compacti􀀌cations on certain geometries is famously estimated at 􀀘 O(10500) . For type IIA string theory there may be in􀀌nite families of  \n􀀍ux vacua [6], though there are believed to be only a 􀀌nite number of possibilities at any given compacti􀀌cation scale [7] .
